Habitat & Geographic Range

Buckelwal

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Choco Brush Finch

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Choco Brush Finch

The Choco Brush-Finch (Atlapetes crassus) is a medium-sized passerine bird in the family Passerellidae, endemic to the humid forests of the Chocó biogeographic region of northwestern Colombia, with possible occurrence into adjacent Ecuador. Brush-finches of the genus Atlapetes are characterised by their boldly patterned plumage — typically combining black, white, yellow, or rufous on the head and underparts — their stout bills adapted for seed cracking and invertebrate foraging, and their tendency to forage in pairs or small groups in dense undergrowth and at forest edges. The Choco Brush-Finch inhabits humid montane and foothill forest understory, particularly in areas with dense shrubbery, bamboo thickets, and secondary growth, at elevations roughly between 400 and 1,700 metres. It forages terrestrially and in low vegetation for seeds, fruit, and invertebrates. Like most Atlapetes species, it produces a musical territorial song used to defend year-round territories. The IUCN classifies this species as Least Concern. The Chocó is one of the world's most important biodiversity hotspots and has high rates of endemism, but continuing deforestation for agriculture and ranching remains the primary long-term threat to species dependent on this humid forest ecosystem.
